The corridors here were very old, and a few people soon reached the upper floor, and here they found four long corridors around the patio, each with a number of iron doors next to it, and each iron door was occupied by a household, and next to the iron door there were two iron windows with fences, and the inside of the house could be faintly seen.

"There's someone in this room." Suki pointed to a window and said, "There's an old lady here!" ”

Lu Yue glanced up at the house number, which said 203, and then he looked inside, and sure enough, he saw an old lady in a red sweater, and there was an ancient TV in front of her, but the strange thing was that she didn't move, just stood there dumbfounded.

"The door is locked." Tang Jian tried to pull the door, but it didn't move.

"Let's see if there are any clues ahead." Lu Yue pointed to a row of iron doors in front of him and said, "We can't afford to waste our time now, now this is the border!" ”

"Got it, alas." Tang Jian finally looked away from the people and furniture inside, and followed Lu Yue and Tang Ning to continue to walk forward, and the next household was also in this situation, the middle-aged man's home was in a mess, and he himself stood like a statue, not moving, almost every house was in this situation.

"It's... Do you want us to go through the maze? Downing wondered. This place is different from the border we entered before, our factory is an infinitely large area, but this place is locked. ”

"Could it be—" Suki cautiously looked into the bottomless patio beside her. Are we going to jump from here? ”

"It's better not to gamble, although it's possible." Lu Yue stretched out his hand and pulled Su Qi back, who was close to the patio, the cement guardrail was only less than half a meter, and he was afraid that Su Qi would accidentally fall down.

"What kind of people would live here?" Tang Jian was puzzled for a while. "This place is so depressing, I won't come to give money!"

"Look!" Downing seemed to notice something, and pointed to a resident in front of him. "Why are the lights on there?"

Lu Yue looked at Tang Ning's hand, and sure enough, he found that the lights were on in a small apartment, and the iron door there was actually open, and there was a crack. There is also a door number on the door: Guardhouse.

"Let's take a look!" Tang Jian said cautiously.

Except for Tang Ning and Tang Jian, Lu Yue and Su Qi were all in contact with such a strange dark spot boundary for the first time, and Lu Yue became very uneasy without a pocket watch and weapons, but fortunately, there seemed to be nothing unusual here except for the gray sense of depression. Tang Ning quickly left, motioned for Lu Yue to take the two girls back, and then he put his hand on the handle and opened the door at once.

There was no danger inside, Lu Yue and Tang Ning cautiously poked inside, only to find that this was a security room, there was only a set of old tables and chairs, an old-fashioned tin lamp and a blackboard, all the residents were recorded on the blackboard, and there was a square grid drawn next to each household, as if Tang Jian had done those single-item fill-in-the-blank questions before, there was a small room next to the security room, and there was light inside, and it didn't seem to be large.

There was a thick file on the table, Tang Ning carefully dismantled the rope, took out the first piece of paper, and Lu Yue looked at it carefully.

"What's written on it?" Suki asked suspiciously, unable to see a word of her position.

"This seems to be a puzzle given to us by the dark spot..."Lu Yue can see things much faster than Tang Ning, and he can quickly complete the reading. It says that there is a female resident missing, her name is Bai Lan, she is a resident of 204, and we need to find her. ”

"Bai Lan, 24 years old, is a medical worker, and rented an apartment about seven days ago." Downing pointed to the blackboard behind him that was full of residents. "The mission this time is very clear, we need to find her, just draw a chalk mark in the spot where she was found."

"What about the paper in the back?" Suki asked.

"It's the personal information of the residents on every floor here." Tang Ning was too tired to drive along the way, so he pulled his chair and sat down. "Come in first, it's cold outside."

Tang Jian and Su Qi walked into the house after hearing this, and Lu Yue showed them the first piece of paper.

"Find the missing Bai Lan... And draw the right symbol on the blackboard to escape..."

"Closing the door to the security room will be considered a start, at which point the paste on the photo will disappear..."

"Finally, it's a clear question, it's to find someone in these households." Lu Yue looked at the large row of residents outside and stretched, and Tang Jian entered the small room of this security room after reading it. "It was better than expected... Finally, it's not those illusions that can't be seen or touched..."

"It's not that simple..."Tang Jian didn't know what he found in that small room. Come to me, there's a notice! ”

"Notice?" Lu Yue hurriedly rushed into the small room, there was nothing in it, but there was an iron panel nailed to the wall, and Lu Yue was taken aback when he saw the words on it.

"Resident Safety Rules?!"
